A length of flexible tube intended to conduct compressed medical air from a medical air cylinder/terminal unit to a medical device that functions with medical air (e.g., ventilators, anaesthesia units, anaesthesia systems, suctions systems and other medical air dependent devices). The gas pressure in the tubing will be low, a "working pressure" (e.g., 3 - 5 bar), having been reduced by a regulator from a high pressure. The tubing is intended for use within a static clinical environment (e.g., intensive care), is colour-coded for medical air, and reinforced (e.g., with woven polyester or cotton). It is available in various lengths, including standard coil lengths. This is a reusable device.
